Key Features Powerful, ultra-concentrated pre-workout formula Comprehensive combination of active ingredients Contains BioCRE™ creatine With CarnoSyn® beta-alanine Contains L-citrulline and L-tyrosine Caffeine-based stimulant formula Supports energy and alertness Designed for intense resistance training Key Ingredients BioCRE™ Creatine BioCRE™ is an anhydrous form of creatine. Creatine helps increase phosphocreatine availability within muscle cells and improves physical performance during successive bursts of short-term, high-intensity exercise. CarnoSyn® Beta-Alanine Beta-alanine helps increase muscle carnosine concentrations. Carnosine buffers the accumulation of acidity during intense exercise, helping support muscular endurance and delay fatigue. A harmless and temporary tingling sensation may occur following beta-alanine consumption. L-Tyrosine L-tyrosine is an amino acid involved in the production of several neurotransmitters. It is commonly included in pre-workout formulas to support alertness, concentration and mental performance during demanding exercise. L-Citrulline L-citrulline is a precursor to L-arginine and supports nitric oxide production. This may help promote blood flow and nutrient delivery to working muscles during exercise. Caffeine Caffeine stimulates the central nervous system, helping improve alertness, concentration and perceived energy. It can also support physical performance during demanding training sessions. Choline Bitartrate Choline contributes to normal lipid metabolism and the maintenance of normal liver function. It is also a precursor to acetylcholine, a neurotransmitter involved in normal nervous system function. Pinus pinaster Pinus pinaster is a natural pine bark extract containing plant polyphenols and antioxidant compounds.
